Catheterization assembly
First Claim
1. A urinary catheterization device comprising:
- a catheter introducer comprising a first guide section including an inlet for receiving a urinary catheter tip and a second guide section including an aperture for releasing said catheter tip, and, optionally, a removable aperture cover, said aperture adapted for contacting a urethral opening;
a hydrophilic catheter comprising a tip having at least one urine inlet, a urine outlet, and an outer surface, at least a urethra-insertable portion of said outer surface being hydrophilic, and said tip being initially disposed in said first guide section;
a flexible walled sheath comprising first and second ends, a lumen, and a length that is less than that of said catheter, said sheath first end being sealingly attached to said catheter at a non-urethra-insertable location on said catheter adjacent to said urine outlet, and said sheath second end being sealingly attached to said first guide section, whereby said catheter tip is initially retained in said first guide section and prevented from slipping into said sheath lumen, and at least said urethra-insertable portion of said catheter being enclosed in said sheath lumen, said sheath lumen adapted for containing a liquid for wetting said enclosed portion of said hydrophilic catheter; and
a diaphragm disposed in said catheter introducer between said first and said second guide sections, and adapted for being pierced by said catheter tip to form a leakage resistant opening for a wetted hydrophilic catheter.

Abstract
A disposable hydrophilic catheterization device for inserting a hydrophilic catheter into the urethra of an individual for the purpose of evacuating the bladder is disclosed. The catheter device includes a catheter introducer, a flexible hydrophilic catheter and a flexible thin-walled sheath. The sheath surrounds the urethra-insertable portion of the catheter, is adapted for containing a wetting liquid, and prevents pooling of the wetting liquid with collected urine. A leak-resistant diaphragm disposed within the catheter introducer is capable of being pierced by the catheter tip to form a leak-resistant orifice around the wetted hydrophilic catheter as it moves through the orifice.

17. A urinary catheterization device comprising:
-
a catheter introducer comprising a first guide section including an inlet for receiving a urinary catheter tip, a diaphragm cover, and a diaphragm disposed between said first guide section and said cover, said diaphragm adapted for being pierced by said catheter tip to form a leakage resistant opening for a wetted hydrophilic catheter;
a hydrophilic catheter comprising a tip having at least one urine inlet, a urine outlet, and an outer surface, at least a urethra-insertable portion of said outer surface being hydrophilic, and said tip being initially disposed in said first guide section;
a flexible walled sheath comprising first and second ends, a lumen, and a length that is less than that of said catheter, said sheath first end being sealingly attached to said catheter at a non-urethra-insertable location on said catheter adjacent to said outlet, and said sheath second end being sealingly attached to said first guide section, whereby said catheter tip is initially retained in said first guide section and prevented from slipping into said sheath lumen, and at least said urethra-insertable portion of said catheter being enclosed in said sheath lumen, said sheath lumen being adapted for containing a liquid for wetting said enclosed portion of said hydrophilic catheter, and, optionally, containing a predetermined amount of said wetting liquid; and
optionally, a urine collection container attached to a said catheter and adapted for receiving said catheter urine outlet, wherein said sheath lumen is not in fluid communication with said container and said wetting liquid is prevented from entering said container.
